This application claims the priority of the Chinese patent application submitted to the State Intellectual Property Office on December 24, 2021, with the application number 202111602012.8 and the application name "A Paging Method, Communication Device, and Computer-Readable Storage Medium", and filed on Priority of a Chinese patent application with application number 202111373274.1 and application title "A Method for Reducing Detection of PO" filed with the State Intellectual Property Office on November 19, 2021, the entire contents of which are incorporated herein by reference.

technical field

The present application relates to the communication field, and in particular to a paging method, a communication device and a computer-readable storage medium.

Background technique

In some communication mechanisms, in order to reduce the power consumption of the terminal equipment, a discontinuous reception (Discontinuous Reception, DRX) cycle is set. Multiple paging occasions (Paging Occasion, PO) are set in the DRX cycle, and the terminal device can wake up in the PO associated with it, receive the paging message (paging message) sent by the network side device, and judge whether there is a need for downlink data take over. Keep the dormant state in other POs, so as to achieve the purpose of reducing power consumption. eDRX is an extended DRX. Each eDRX cycle includes multiple DRX cycles, and a paging time window (Paging Time Window, PTW) is set in the eDRX cycle. Terminal devices can sleep according to the DRX cycle within the PTW in the eDRX cycle. Or receive paging messages, further saving power.

However, currently in the eDRX cycle, if the network side device sends a paging message at the PO associated with the terminal device, the terminal device needs to wake up at the PO to receive the paging message, if the paging message does not carry the paging message of the terminal device (that is, the terminal device has not been paged), then the terminal device needs to continue to wake up at the PO associated with it in the next DRX cycle, and continue to receive paging messages until each PO associated with it in the PTW is monitored over. That is to say, when the network side device does not page the terminal device, the terminal device may need to monitor each PO associated with it in the PTW, causing unnecessary power consumption of the terminal device.

The system message includes multiple system information blocks (System Information Block, SIB).

For example, the first system message may be SIB1, and the network side device may add an information element to SIB1 as the first indication information. The second system message may be SIB2, and the network side device may add an information element to SIB2 to indicate group indication information (that is, the above-mentioned second indication information or third indication information).

In the case of multiplexing, the network side device may send only one second PEI at q POs, and the terminal device only needs to receive the second PEI once, thereby saving power consumption. If the paging status within q DRX cycles cannot be predicted, the network-side device can choose not to multiplex the second PEI, so that the network-side device can flexibly and timely page the associations at each PO according to the burst traffic. terminal equipment, thereby reducing paging delay.

Optionally, if the fourth indication information indicates no multiplexing, the terminal device may not recognize the fourth indication information carried in the third PEI after each PO located after the first PO receives the corresponding third PEI.

Wherein, one or more POs at the same position in K DRX cycles can be understood as one or more POs with the same sequence number (or index, numbering) in paging frames at the same position in K DRX cycles. For a terminal device, since there is only one PO corresponding to the terminal device in one DRX cycle, the PEI received by the terminal corresponds to the K POs of the terminal device, that is, the terminal device receives one PEI, which can be It is determined according to the PEI whether the terminal equipment needs to wake up to receive paging messages at the K associated POs.

Based on this possible scenario, the network side device may carry the first indication information in the PEI (hereinafter, the PEI carrying the first indication information is referred to as the first PEI), or may carry the first indication information in the paging message .

For example, optionally, the eDRX includes K POs associated with the terminal device, the K POs are respectively located in K DRX cycles, K≥1, K is an integer, and the sending of the first indication information, include:

Wherein, at least one PO includes the PO after the J-th PO among the K POs, or at least one PO includes the PO after the J-th PO in the eDRX cycle, 1≤J≤K, and J is an integer.

It can be understood that since the paging message is sent periodically, the network side device configures the first indication information in the paging message, which can increase the reliability of the terminal device receiving the first indication information.

For example, the first system message may be SIB1, and the network side device may add an information element to SIB1 as the first indication information. The second system message may be SIB2, and the network side device may add an information element to SIB2 to indicate group indication information (that is, the above-mentioned second indication information or third indication information).

In the case of multiplexing, the network side device may send only one second PEI at q POs, and the terminal device only needs to receive the second PEI once, thereby saving power consumption. If the paging status within q DRX cycles cannot be predicted, the network-side device can choose not to multiplex the second PEI, so that the network-side device can flexibly and timely page the associations at each PO according to the burst traffic. terminal equipment, thereby reducing paging delay.

Optionally, in a possible scenario, the network side device configures the eDRX cycle and the fourth PEI for the terminal device. The PTW in the eDRX cycle includes r DRX cycles, the fourth PEI is configured to correspond to one or more POs located at the same position in the q DRX cycles, r≥q≥1, and both q and r are integers. Wherein, the q DRX cycles may be continuous or discontinuous. The fourth PEI includes a bitmap corresponding to each group of terminal devices in each PO. Based on this PEI configuration method, the network side device can predict the paging situation at each PO corresponding to the fourth PEI in advance, so that a fourth PEI can be sent at q POs, and the terminal device only needs to receive the first With four PEIs, it can be determined whether the q POs need to wake up to receive paging messages, thereby saving the power consumption of the terminal equipment.

Wherein, the access network device may also be called a radio access network (radio access network, RAN) or a radio access network device, and the access network device may be a transmission reception point (transmission reception point, TRP), or an LTE The evolved base station (evolved NodeB, eNB or eNodeB) in the system can also be a home base station (for example, home evolved NodeB, or home Node B, HNB), a base band unit (base band unit, BBU), or a cloud wireless The wireless controller in the access network (cloud radio access network, CRAN) scenario, or the access network device can be a relay station, an access point, a vehicle device, a wearable device, and a network device in a 5G network or a future evolved PLMN The network equipment in the network can also be an access point (access point, AP) in the WLAN, or a gNB in the NR system. The above-mentioned access network equipment can also be a city base station, a micro base station, a pico base station, a nano Femto base stations and the like, which are not limited in this application. For example, the access network device is used for information exchange with the terminal device.

For example, the core network equipment may include core network access and mobility management function (core access and mobility management function, AMF), user plane function (user plane function, UPF) network element, session management function (session management function, SMF) At least one of network element, data network (data network, DN), unified data storage (unified data repository, UDR) or unified data management (unified data management, UDM).

In some communication mechanisms, in order to reduce power consumption of the terminal device, the network side device may control the terminal device to sleep by configuring a DRX cycle. Multiple POs are set in the DRX cycle, and each PO can be associated with multiple terminal devices, and one terminal device is associated with one PO in one DRX cycle. During the DRX period, the terminal device will wake up at the associated PO (that is, turn on the receiving circuit to receive downlink data) and monitor paging. If paged, the terminal equipment enters connected (connection) state. For example, if the terminal device is in an idle (idle) state, after being paged, it will initiate an RRC connection request (RRC connection request), that is, initiate random access, to enter the connected state from the idle state. If the terminal device is in the inactive (inactive) state, after being paged, it will initiate an RRC connection resume request (RRC connection resume request) to enter the connected state from the inactive state. If it is not paged, it will continue to maintain the idle (idle) state or inactive (inactive) state, and sleep at other POs (that is, turn off the receiving circuit and not receive downlink data). Hereinafter, for the convenience of description, sometimes the PO associated with the terminal device is also referred to as the PO of the terminal device.

For example, as shown in FIG. 2, a DRX cycle includes multiple paging frames (Paging Frame, PF), and each paging frame corresponds to multiple POs (for example, 10 POs including PO0, PO1, ..., PO9). Suppose UE1, UE2, ..., UE6 are associated with PO0 in the first paging frame. The six terminal devices UE1, UE2, ..., UE6 will wake up at PO0 of the first paging frame in each DRX cycle, and monitor paging. If the network side device wants to page UE1, it will page UE1 at PO0 of the first paging frame. If the access network device in the network side device pages UE1, the access network device will send a paging message to UE1; if the core network device in the network side device pages UE1, the core network device will send a paging message to the access The network device sends information for paging UE1, such as UE1's identifier, time-frequency resource location information, etc., and then the access network device sends a paging message to UE1 according to the information sent by the core network device.

After UE1 receives the paging message, it can initiate the RRC connection request or RRC connection resume request process and enter the connected state. For UE2 to UE6, since they are not paged at PO0, UE2 to UE6 continue to maintain the idle state or inactive state, and re-enter the dormant state.

In some communication mechanisms, an eDRX cycle is also set. eDRX is extended DRX (extended DRX). For example, as shown in Figure 2, each eDRX cycle includes multiple DRX cycles, and a paging time window PTW is set in the eDRX cycle. In PTW, receive paging messages in DRX mode, and stay dormant outside PTW. Based on different communication mechanisms, the duration of the DRX cycle and the eDRX cycle are set in different configuration ranges according to the type (or service type) of the terminal equipment. For example, in the current protocol definition, the maximum duration of the DRX cycle can be configured as approximately 2.56 seconds. In enhanced Machine-Type Communication (eMTC), the maximum eDRX cycle that can be configured for terminal devices in idle state is about 44 minutes, and the maximum eDRX cycle that can be configured for terminal devices in inactive state is 10.24 seconds. Narrow Band Internet of Things (NB-IoT) currently does not support the inactive state. Therefore, the maximum eDRX cycle that can be configured for terminal devices in the idle state in NB-IoT is about 3h.

It can be seen that by configuring a larger eDRX cycle and a smaller PTW, the terminal can sleep for more time and obtain a greater power consumption gain; but it will increase the corresponding paging delay. For example, if the terminal device does not successfully receive the paging message within the PTW, or the data of the terminal device reaches the network side device outside the PTW, the network side device can only page the terminal device at the PTW in the next eDRX cycle , at this time, a larger eDRX cycle will cause a larger paging delay.

In order to further reduce the power consumption of terminal equipment during the paging process, the concept of Wake Up Signal (WUS) is introduced in R15NB-IoT. WUS is used to indicate that there is a paging message sent at the PO. For example, when the access network device determines that the paging message will be delivered at a PO, the WUS may be sent at a certain offset (offset) position before the PO. The location where the WUS is sent may be protocol specific. For example, UE1 to UE6 associated with PO0 will wake up at the specified offset position before PO0. If WUS is received, it means that the access network device will send a paging message at PO0, and UE1 to UE6 will wake up at PO0. to receive paging messages. If no WUS is received at the specified offset position before PO0, UE1 to UE6 can stay dormant at PO0 without waking up to listen for paging, thereby saving power consumption.

The introduction of WUS also brought about the problem of false alarms. For example, if the network side device needs to page UE1, but does not page UE2 to UE6, the network side device will also send WUS at the offset position specified before PO0. In this case, the WUS makes a false alarm to UE2 to UE6, so that UE2 to UE6 need to wake up at PO0 even if they are not paged, which wastes the power consumption of UE2 to UE6. To this end, the concept of Group Wake Up Signal (GWUS) was introduced. The GWUS is used to indicate which groups of end devices have paging messages at the associated PO. The network side device divides multiple terminal devices associated with each PO into multiple different WUS group sets (WUS groups) according to the paging probability of the terminal device, and the terminal device can be determined according to the identifier (ID) of the terminal device. The group number of the WUS group where the device is located. For example, the network side device determines UE1 as WUS group1, UE2 and UE3 as WUS group2, UE4 as WUS group3, UE5 and UE6 as WUS group4, that is, PO0 is associated with 4 groups of terminal devices. When the network side device determines that UE1 needs to be paged, the network side device determines the group number of WUS group1 according to the ID of UE1, and the network side device determines that terminals in WUS group1 need to receive paging messages, but terminal devices in WUS group2 to WUS group4 do not need to receive paging messages. paging message. Therefore, the network side device can issue the GWUS corresponding to WUS group1 at the offset position specified before PO0. After UE1 receives the GUWS corresponding to WUS group1, it can wake up at PO0 to receive paging messages; UE2 to UE6 can keep sleeping at PO0 after receiving GWUS not in this group, so as to save power consumption and reduce the probability of false alarms.

In a possible implementation manner, the network side device configures the eDRX cycle and the GWUS for the terminal device, and the GWUS can be associated with multiple POs (such as 1, 2 or 4 POs). The multiple POs may be respectively located in multiple DRX cycles and associated with the same terminal device. Taking GWUS associated with 4 POs as an example, one GWUS can instruct UEs in the same group to wake up at corresponding POs in 4 consecutive DRX cycles. For example, UE1 to UE6 are associated with the PO0 corresponding to the first paging frame in the DRX cycle, then in the PTW, the PO0 corresponding to the first paging frame in four consecutive DRX cycles can be indicated by a GWUS.

For example, suppose the network side device determines that UE2 needs to be paged, and the network side device obtains the group number of WUS group2 associated with PO0 according to the ID of UE2, so the network side device determines that the offset position that needs to be specified before PO0 in the first DRX cycle Issue the GWUS corresponding to WUS group2 to instruct the terminal devices of WUS group2 (ie UE2 and UE3) to receive paging messages at PO0. After UE1 to UE6 receive the GWUS, UE2 and UE3 receive the paging message at PO0, and UE1, UE4 to UE6 can keep sleeping in 4 consecutive DRX cycles. After UE2 receives the paging message at PO0, it determines that it is paged (that is, it detects that the paging message carries the identity of UE2), and UE2 enters the connected state. After UE3 successfully receives the paging message at PO0 and determines that it has not been paged (that is, it detects that the paging message does not carry the identity of UE3), UE3 needs to continue to wake up at the next PO0 and receive the paging message until 4 PO0s in 4 consecutive DRX cycles are monitored.

That is to say, although the introduction of GWUS can reduce the power consumption of each terminal device in the group that has not been paged, for example, the terminal devices in the WUS group1, WUS group3, and WUS group4 that have not been paged in the above example (including UE1, UE4 to UE6), but for the terminal equipment that is not paged in the paged group, such as UE3 in WUS group2, it still needs to wake up and listen for paging at each associated PO without being paged, There is a problem of wasted power consumption.

WUS and GWUS are concepts proposed in LTE to reduce the power consumption of terminal equipment during the paging process. In NR, in order to reduce the power consumption of terminal equipment during the paging process, Paging Early Indication (Paging Early Indication, PEI) concept. The PEI is used to indicate whether each group of terminal devices associated with a PO wakes up at the PO to receive paging messages. In the current discussion on PEI, one PEI can correspond to multiple POs in DRX; PEI can be represented by a new downlink control information (Downlink Control Information, DCI) format, and 1 bit in the DCI can be used to indicate a PO Whether one or more groups of terminal devices at the location need to wake up to receive paging messages.

For example, as shown in FIG. 3 , the PEI corresponds to the four POs corresponding to the first paging frame in the DRX cycle, namely PO0, PO4, PO5 and PO9. The PEI includes a 16-bit sequence or bitmap (bitmap), and each 4 bits indicates 4 groups of terminal equipment in a PO. It should be noted that for a specific UE, there is only one PO corresponding to the UE in a DRX cycle, that is, the UE only needs to wake up once in a DRX cycle. Therefore, UEs corresponding to all bits in the PEI are different UEs. For example, when the network side device configures the PEI as "0101 0001 0111 1101" according to the ID of the terminal device to be paged, the PEI is used to instruct the network side device to send paging messages at PO0, PO4, PO5 and PO9 , terminal devices in WUS group2 and WUS group4 associated with PO0 need to wake up at PO0 to receive paging messages, terminal devices in WUS group1 and WUS group3 associated with PO0 can sleep at PO0; WUS group4 associated with PO4 The terminal devices in PO4 need to wake up to receive paging messages, and the terminal devices in WUS group1 to WUS group3 associated with PO4 can sleep at PO4; the terminal devices in WUS group2 to WUS group4 associated with PO5 need to be in PO5 Wake up at PO5 to receive paging messages, the terminal devices in WUS group1 associated with PO5 can sleep at PO5; the terminal devices in WUS group1, WUS group2 and WUS group4 associated with PO9 need to wake up at PO9 to receive paging messages , terminal devices in WUS group3 associated with PO9 can sleep at PO9.

In the current discussion on PEI, it has been agreed that one PEI can correspond to one or more POs in one DRX. But at this time, the terminal device needs to wake up to receive the PEI before each associated PO, resulting in certain power consumption. In order to further reduce power consumption, the possibility that one PEI corresponds to multiple POs in eDRX is being discussed in existing standards. However, one PEI corresponds to multiple POs in eDRX, and there is still a problem of power consumption waste: that is, if only some terminal devices in the same group of terminal devices are paged, then the unpaged terminal devices also need to The PO wakes up and listens for paging.

For this reason, the present application provides a paging method, which can reduce the power consumption of terminal equipment. The paging method provided by this application can reduce the power consumption of the terminal equipment from two aspects. On the one hand, when the terminal equipment is not being paged, it reduces the number of times the terminal equipment wakes up to receive paging messages, so as to save the power consumption of the terminal equipment. Power consumption; on the other hand, it saves the power consumption of the terminal equipment by reducing the number of times the terminal equipment wakes up to receive PEI/GWUS.

The paging method provided by the present application will be exemplarily described below in combination with specific embodiments.

Referring to FIG. 4 , it is a flow chart of an embodiment of a paging method provided by the present application, which mainly involves a solution for reducing the number of times a terminal device wakes up to receive paging messages. As shown in Figure 4, the paging method includes:

S401. The network side device sends first indication information, where the first indication information indicates that when the paging message received by the terminal device in the eDRX cycle does not carry the identity of the terminal device, the information associated with the terminal device in the eDRX cycle At least one PO remains dormant.

S402. When the paging message received by the terminal device does not carry the identifier of the terminal device, the terminal device maintains a dormant state at at least one PO associated with the terminal device in the eDRX cycle according to the first indication information.

In the embodiment of the present application, the network side device sends the first indication information to indicate that the terminal device can remain in a dormant state at least one associated PO without waking up to receive the paging message if it is not being paged. Thereby, the power consumption of the terminal equipment is saved.

Wherein, the network side device may deliver the first indication information through an independent message, or carry the first indication information in some messages and deliver the first indication information to each terminal device. For example, the network side device may carry the first indication information in PEI, GWUS, system message, paging message and other messages and send it to each terminal device. The paging method shown in FIG. 4 is exemplarily described below in conjunction with several possible scenarios.

In the first possible scenario, the network side device configures the eDRX cycle and PEI for the terminal device. The PTW in the eDRX cycle includes r DRX cycles, the PEI is configured to correspond to one or more POs located at the same position in the K DRX cycles, r≥K≥1, and K and r are both integers.

Among them, one or more POs at the same position in K DRX cycles can be understood as one or more POs with the same sequence number (or index, number) corresponding to the paging frame at the same position in K DRX cycles .

It should be noted that the paging frame at the same position in the DRX cycle means that the paging frame has the same position in each DRX cycle (for example: the first paging frame in each DRX cycle), and the same position in the DRX cycle The frame numbers of the paging frames can be different.

For example, as shown in FIG. 5 , the PEI is configured to correspond to 2 POs (PO0, PO4) corresponding to the first paging frame in each DRX cycle within K DRX cycles. That is, in this scenario, the PEI is configured to correspond to K (1<K<r in Figure 5 as an example) DRX cycles, and the PEI specifically corresponds to the first paging frame corresponding to the first paging frame in each DRX cycle. PO and the third PO (that is, PO0 and PO4). For a terminal device, since there is only one PO corresponding to the terminal device in a DRX cycle, the received PEI corresponds to K POs of the terminal device, that is, the terminal device receives a PEI, which can be calculated according to The PEI determines whether the terminal device needs to wake up to receive paging messages at the K associated POs.

Exemplarily, the PEI includes an 8-bit bitmap (bitmap), and each 4 bits indicates 4 groups of terminal devices in a PO. For example, when the network side device configures the PEI as "0101 0001" according to the ID of the terminal device to be paged, the PEI is used to instruct the network side device to send paging messages at PO0 and PO4, and the WUS associated with PO0 The terminal devices in group2 and WUS group4 need to wake up at PO0 to receive paging messages, the terminal devices in WUS group1 and WUS group3 associated with PO0 can sleep at PO0; the terminal devices in WUS group4 associated with PO4 need to be in Wake up at PO4 to receive paging messages, and the terminal devices in WUS group1 to WUS group3 associated with PO4 can sleep at PO4.

For any terminal device associated with PO0 and PO4, for example, for terminal device UE2 in WUS group2 associated with PO0, the PEI shown in FIG. 5 corresponds to K PO0s. According to the PEI shown in Figure 5, UE2 can determine that the network side device will send a paging message at PO0 corresponding to the first paging frame in consecutive K DRX cycles, and UE2 needs to wake up and listen for paging.

It can be understood that, if K=r, for POs at the same position in each DRX cycle in the entire PTW, the network side device can send PEI once at most for indication. In this way, the terminal device can receive a PEI for all associated POs in the entire PTW without performing a PEI reception for each associated PO, thereby reducing the number of times of receiving PEIs and saving power consumption. For example, when K=r, if there is a terminal device to be paged at any PO of PO0 and PO4, the network side device can place the specified offset position before PO0 in the first DRX cycle in PTW Issue the PEI, through which the PEI indicates whether there is a paging message at PO0 and PO4 corresponding to the paging frame at the same position in each DRX cycle in the entire PTW, and which groups of terminal devices in the corresponding PO need to wake up to receive the paging message .

If K=1, it means that within the PTW of the eDRX cycle, the terminal device needs to receive the PEI before each corresponding PO, so as to determine whether it needs to wake up to receive the paging message at the PO.

If 1<K<r, it means that within the PTW of the eDRX cycle, every K DRX cycle can be regarded as a PEI sending cycle. instruct. In this way, the terminal device can perform one PEI reception for all associated POs in one PEI sending cycle, and does not need to perform one PEI reception for each associated PO, thereby reducing the number of times of receiving PEI and saving the power consumption of the terminal device .

Based on the foregoing first possible scenario, in a possible implementation manner, the network side device may carry the first indication information in the PEI and send it to each terminal device. For ease of description, the PEI carrying the first indication information is referred to as the first PEI hereinafter. In this case, for a terminal device, if the first PEI indicates that the network side device will send paging messages at K POs associated with the terminal device, the terminal device will Monitor paging at K POs until the first paging message is successfully received. When it is detected that the paging message does not carry the identifier of the terminal device, the terminal device may maintain a sleep state at least one PO associated with the terminal device in the eDRX cycle according to the first indication information carried in the first PEI .

Wherein, at least one PO includes a PO that is located after the first PO among the K POs, or at least one PO includes a PO that is associated with the terminal device after the first PO in the eDRX cycle, and the first PO is that the terminal device is in the K The PO where the first paging message is successfully received at the PO.

Exemplarily, the network side device may add a one-bit information element at the front end or tail end of the PEI to identify the first indication information. For example, based on the PEI shown in Figure 5, one bit can be added at the end of the PEI to obtain the first PEI "0101 0001 1" as shown in Figure 6.

In combination with the first PEI shown in FIG. 6 , it is assumed that the network side device issues the first PEI shown in FIG. 6 because it needs to page UE2, and the first PEI indicates that the network side device will send a paging message at PO0, End devices in WUS group2 associated with PO0 (for example, including UE2 and UE3) need to wake up at PO0 to receive paging messages. After sending the first PEI, the network side device will send a paging message for paging UE2 at K PO0s, and the paging message carries the identifier of UE2. Since the network side device does not page UE3, the paging message does not carry the identifier of UE3.

UE2 wakes up and monitors paging at K PO0s according to the instruction of the first PEI until UE2 successfully receives the first paging message. When UE2 determines that the paging message carries the identity of UE2, UE2 will enter the connected state and prepare to receive corresponding downlink data subsequently. It can be understood that UE2 may successfully receive the first paging message at the first PO0, or may successfully receive the first paging message at the second or third PO0. UE2 can enter the connected state after successfully receiving the first paging message and confirming that the paging message carries the identity of UE2.

UE3 receives the paging message at K PO0s according to the indication of the first PEI until UE3 successfully receives the first paging message. When it is determined that the paging message does not carry the identity of UE3, UE3 may maintain a dormant state at at least one PO0 in the eDRX cycle according to the first indication information carried in the first PEI.

Wherein, at least one PO0 includes the PO0 after the first PO among the K PO0s, where the first PO refers to the PO0 where UE3 successfully receives the first paging message at the K PO0s. For example, UE3 may successfully receive the first paging message at the first PO0, and at this time, the first PO0 is the first PO. UE3 may also not receive the first paging message at the first PO0, or fail to receive the first paging message, and UE3 needs to wake up at the second PO0 and continue to monitor paging. If the paging message is successfully received at the second PO0, the second PO0 is the first PO.

Exemplarily, K=4, UE3 successfully receives the first paging message at the first PO0, UE3 determines that the paging message does not carry the identity of UE3 by detecting the paging list carried in the paging message, UE3 can maintain a sleep state at the remaining three PO0s according to the first indication information, thereby saving power consumption.

Optionally, at least one PO0 includes PO0s located after the first PO in the eDRX cycle. For example, when K<r, assuming that r=10 and K=8, r DRX cycles include 2 PEI sending cycles. Assuming that UE3 successfully receives the first paging message at the first PO0 in the first PEI sending cycle, and confirms that the paging message does not carry the identity of UE3, UE3 can then The remaining 7 PO0s remain in a dormant state within 1 PEI sending cycle. In addition, since there are only 2 PO0s left in the eDRX cycle (the 2 PO0s in the second PEI sending cycle), when the network device estimates that UE3 does not need to receive paging messages at the remaining 2 PO0s, UE3 also Can stay dormant at 2 PO0s within the 2nd PEI sending cycle. That is to say, when UE3 is not being paged, it only needs to wake up to monitor paging at the first PO0, and does not need to wake up to monitor paging at the subsequent 9 PO0s, which greatly reduces UE3 wake-up time. The number of times to receive paging messages, and there is no need to wake up to receive PEI in the second PEI sending cycle, thereby saving the power consumption of UE3.

In an example, when K=1, at least one PO may include POs associated with the terminal device located after the first PO in the eDRX cycle. For example, UE3 receives the first PEI shown in Figure 6 before the ninth PO0 in the eDRX cycle. According to the indication of the first PEI, UE3 wakes up at the ninth PO0 to receive the paging message. If UE3 receives the paging message and determines that the paging message does not carry the identity of UE3, UE3 can keep sleep. And a possible situation is that UE3 does not need to wake up to monitor the PEIs corresponding to the remaining r-9 PO0s, thereby saving the power consumption of receiving PEIs and saving the power consumption of monitoring paging messages.

Based on the foregoing first possible scenario, in another possible implementation manner, the network side device may carry the first indication information in a paging message and send it to a corresponding terminal device. For example, when the network device sends paging messages to K POs, the paging message sent to the Jth PO in the K POs carries the first indication information. When the terminals associated with the K POs After the device successfully receives the paging message at the Jth PO, it can obtain the first indication information from the paging message. When it is detected that the paging message does not carry the identifier of the terminal device, the terminal device may maintain a sleep state at least one PO associated with the terminal device in the eDRX cycle according to the first indication information.

When the network side device delivers the paging message, it may determine which paging messages carry the first indication information according to the number of terminal devices to be paged. Assume that the network side device needs to deliver paging messages at K PO0s. In an example, if the network side device determines that the number of terminal devices to be paged at PO0 does not exceed the maximum number of paging (for example, 32) that PO0 can support, then as shown in (a) in Figure 7, The network side device may carry the first indication information in the paging message delivered by each PO0, so as to ensure that the terminal equipment associated with the PO0 can receive the paging message carrying the first indication information.

For the terminal device associated with PO0, the terminal device may successfully receive the first paging message at the Jth PO0. For example, UE3 successfully receives the first paging message at the second (when J=2) PO0. If UE3 detects that the paging message does not carry the identity of UE3, and detects the first indication information in the paging message, the terminal device can remain in the dormant state at the remaining K-2 PO0s, or in the eDRX cycle All PO0s behind the PO0 where the paging message is received within the internal location remain dormant.

In another example, if the network side device determines that the number of terminal devices paged at PO0 exceeds the maximum paging number (for example, 32) that PO0 can support, the network side device does not carry the first Indication information; when the paging message can page all terminal devices, the first indication information is carried in the paging message.

For example, the network side device needs to page 40 terminal devices at PO0, exceeding the maximum number of paging 32 that can be supported at one PO. Then the paging message sent by the network side device at the first PO0 carries part of the identifiers of the terminal devices to be paged (for example, 32 identifiers can be carried), and the paging message sent at the second PO0 carries The identifiers of the remaining terminal devices to be paged are used to completely page all the terminal devices that need to be paged. In this case, since the paging message sent by the network side device at the second PO0 can page all the terminal devices that need to be paged, the network side device can send the paging message at the second PO0 The message carries the first indication information.

It can be understood that since the paging message is sent periodically, as shown in (b) in Figure 7, then at K PO0s, the network side device may be at the second PO0, the fourth PO0, ... 1. The paging message delivered by the Kth PO0 carries the identities of the remaining 8 terminal devices, then the network side device may carry the first indication information in these paging messages.

For the terminal device associated with PO0, the terminal device may successfully receive the first paging message at the Jth PO0. For example, UE3 successfully receives the first paging message at the fourth (when J=4) PO0. If it is detected that the paging message does not carry the identity of UE3, and the first indication information is detected in the paging message, UE3 may remain in the dormant state at the remaining K-4 PO0s, or be located in the eDRX cycle All PO0s following the PO0 where the paging message is received remain dormant.

It can be understood that since the paging message is sent periodically, the network side device configures the first indication information in the paging message, which can increase the reliability of the terminal device receiving the first indication information. In one implementation, a terminal device configured with eDRX and PEI can parse and read the first indication information carried in the paging message, while a terminal device not configured with eDRX and PEI does not need to parse and read the first indication information after receiving the paging message. The first indication information carried in the paging message.

In the second possible scenario, the network side device configures the eDRX cycle for the terminal device, and configures the grouping of POs in the eDRX cycle.

In this scenario, the network side device can configure the grouping status of POs through an independent message, and can also carry grouping indication information in some messages to indicate the grouping status of POs. For example, group indication information may be carried in system messages, radio resource control (Radio Resource Control, RRC) messages, and DCI. The following uses system messages as an example to illustrate the second scenario and the paging method implemented based on the second scenario.

The network side device sends the group indication information and the first indication information to the terminal device through a system message.

In a possible implementation manner, the network side device may send the first indication information and the grouping indication information to the terminal device through different system messages. For example, the network side device may send a first system message to the terminal device, and carry the first indication information in the first system message; and the network side device may send a second system message to the terminal device, and carry the grouping indication information in the first system message; Two system messages.

Wherein, the system information includes multiple system information blocks (System Information Block, SIB). Exemplarily, the first system information may be SIB1, and the network side device may add an information element in SIB1 as the first indication information. The second system message may be SIB2, and the network side device may add an information element to SIB2 to indicate group indication information.

In an example, the group indication information may be second indication information, and the second indication information is used to instruct the network side device to send the same paging message at n POs, where the n POs are the first n POs in the eDRX cycle and For the PO associated with the terminal device, n≥2, where n is an integer. Correspondingly, the at least one PO where the terminal device sleeps includes the PO located after the second PO among the n POs, and the second PO is the PO where the terminal device successfully receives the first paging message at the n POs.

For example, taking UE3 as an example, as shown in (a) in Figure 8, the PTW in the eDRX cycle includes r (r≥n) PO0s associated with UE3, and the r PO0s are respectively located in r DRX cycles in the PTW . After UE3 receives the second indication information through the second system message, it can determine according to the second indication information: if the network side device sends a paging message at PO0, it will send the same paging message to the first n PO0s in the PTW. paging message.

When the network side device sends paging messages at the first n PO0s in a certain eDRX cycle, if UE3 successfully receives the first paging message at the first PO0, the first PO0 is the first Two POs. UE3 determines according to the first indication information received through the first system message that UE3 can stay dormant at n-1 PO0s after the first PO0. That is to say, in the case of not being paged at the first n PO0s, the UE3 can stay in a dormant state at n-1 PO0s without waking up to monitor paging, thereby saving power consumption of the terminal equipment.

For the remaining r-n PO0s, UE3 can wake up at each PO0 to monitor paging. Of course, if the network side device also configures GWUS/WUS/PEI for the terminal device at the same time, the terminal device can also determine whether the GWUS/WUS/PEI is issued by the network side device and the content of the issued GWUS/WUS/PEI. Whether to stay asleep or wake up to listen for paging at the corresponding PO0.

Optionally, the grouping indication information may be third indication information, and the third indication information is used to indicate that multiple POs associated with the terminal device within the PTW in the eDRX cycle include m PO groups, and each PO group includes p PO. The network side device sends the same paging message to p POs in each PO group, m≥2, p≥2, m and p are both integers. Correspondingly, the terminal device determines according to the first indication information that at least one PO that can be dormant includes POs located after the third PO in the PO group, and the third PO is when the terminal device successfully receives the first paging message in the PO group The PO where it is located.

Wherein, the p POs in each PO group may be consecutive POs in the PTW. For example, the PTW in the eDRX cycle includes r (r>m, and r≥p) PO0s associated with UE3, and the r PO0s are respectively located in r DRX cycles in the PTW. For example, as shown in (b) in FIG. 8 , every p consecutive PO0s are divided into a PO group, for example, the first p PO0s are the first PO group.

Optionally, the p POs in each PO group may be discontinuous POs in the PTW. For example, p=4, the first PO group can include the 1st, 3rd, 5th, and 7th PO0s in the PTW; the second PO group can include the 2nd, 4th, 6th, and 8th PO0s in the PTW; the third PO The group can include the 9th, 11th, 13th, and 15th PO0s in the PTW; the fourth PO group can include the 10th, 12th, 14th, and 16th PO0s in the PTW, etc.

Take UE3 and the PO group shown in (b) in FIG. 8 as an example. After UE3 receives the third indication information through the second system message, it can determine according to the third indication information that r PO0s include m PO groups, and each PO group includes p POs. If the network side device needs to send paging message, the same paging message will be sent to each PO group.

For example, as shown in (b) in Figure 8, when the network side device sends a paging message in the first PO group, if UE3 successfully receives the paging message at the first PO0 in the first PO group 1 paging message, in the first PO group, the first PO0 is the third PO. UE3 determines according to the first indication information received through the first system message that it can stay dormant at p-1 PO0s after the first PO0. That is to say, in the first PO group, when not being paged, UE3 can stay in sleep state at the remaining p-1 PO0s without waking up to monitor paging, thereby saving the power consumption of the terminal equipment.

When the network side device sends a paging message in the second PO group, if UE3 successfully receives the first paging message at the third PO0 in the second PO group, the Among them, the third PO0 is the third PO. UE3 determines according to the first indication information received through the first system message that it can stay dormant at p-3 PO0s after the third PO0. That is to say, in the second PO group, when not being paged, UE3 can keep sleeping at p-3 PO0s without waking up to monitor paging, thereby saving the power consumption of the terminal equipment.

Based on the second possible scenario, in another possible implementation manner, the network side device may simultaneously carry the first indication information and the group indication information in one system message. That is, the first system information and the second system information are the same SIB, and a bit is added to the SIB to identify the first indication information, and an information element is added to indicate the group indication information.

Optionally, in yet another possible implementation manner, the grouping indication information may serve as the first indication information at the same time. That is, when the network side device sends grouping indication information to the terminal device through the system information, the terminal device can determine the PO grouping situation according to the grouping indication information: when the terminal is not paged, the terminal device can In the eDRX period, at least one PO associated with the terminal equipment remains in a dormant state, so as to save power consumption.

In the third possible scenario, the network side device configures the eDRX cycle and PEI for the terminal device. The PTW in the eDRX cycle includes r DRX cycles, and the PEI is configured to correspond to one or more POs in one DRX cycle, and the network side device can judge whether the PEI is in the same position in q DRX cycles according to the paging situation Multiplexing at one or more POs at , r≥q≥1, K and r are both integers. Wherein, the q DRX cycles may be continuous or discontinuous.

Among them, one or more POs located at the same position in q DRX cycles can be understood as one or more POs with the same sequence number (or index, number) corresponding to the paging frame at the same position in q DRX cycles . Similarly, the paging frame at the same position in the DRX cycle refers to the same position of the paging frame in each DRX cycle (for example: the first paging frame in each DRX cycle), and the paging frame at the same position in the DRX cycle The frame numbers of the frames can be different.

Based on the third possible scenario, see FIG. 9 , which is a flow chart of an embodiment of a paging method provided by the present application, which mainly involves a solution for reducing the number of times a terminal device wakes up to receive PEI. As shown in Figure 9, the paging method includes:

S901. The network side device issues a second PEI, where the second PEI carries fourth indication information, and the fourth indication information is used to indicate whether the terminal equipment multiplexes the second PEI at q POs.

The so-called q POs refer to POs for the same terminal device, which are respectively located in q DRX cycles. For example, as shown in FIG. 10 , q=2, and the second PEI corresponds to PO0 and PO4 corresponding to the first paging frame in two consecutive DRX cycles. The second PEI includes a 9-bit bitmap. It is assumed that the first 4 bits indicate 4 groups of terminal equipment in a PO0, the middle 4 bits indicate 4 groups of terminal equipment in a PO4, and the last bit indicates the fourth indication information. For example, assigning a value of "1" to the last bit indicates multiplexing, and assigning a value of "0" to the last bit indicates not multiplexing. Or by assigning a value "0" to the last bit to indicate multiplexing, and assigning a value to the last bit to "1" to indicate no multiplexing. For any terminal equipment associated with PO0 and PO4, for example, for terminal equipment UE2 in WUS group2 associated with PO0, it can be determined whether the second PEI is multiplexed at two PO0s according to the fourth indication information .

In an example, the network side device can determine the paging situation by predicting whether the paging terminal devices at q POs are the same, or according to whether the paging terminal devices at q POs can be predicted, or according to the paging list , to determine whether to reuse or not to reuse.

For example, if the network side device determines that the paging lists at q POs are the same, the fourth indication information is configured to indicate multiplexing. Alternatively, if the network side device determines that the number of terminal devices to be paged exceeds the maximum number of paging that a PO can support, the fourth indication information is configured to indicate multiplexing. For example, when the number of terminal devices to be paged exceeds the maximum number of pages that a PO can support, the network side device cannot carry the identifiers of all the terminal devices to be paged in a paging message, so the network side device will The identifiers of the terminal devices to be paged are carried in batches in multiple paging messages and delivered. The terminal device did not detect the identity of the terminal device in the first paging message, possibly because the terminal device was not paged, or because the identity of the terminal device was carried in the subsequent paging message, Therefore, the terminal device needs to wake up at the next associated PO to continue listening to the paging message. In this case, in order to ensure that the terminal device to be paged can receive the corresponding paging message, the network side device may configure the fourth indication information as indicating multiplexing.

If the paging lists at the q POs are different, configure the fourth indication information to indicate no multiplexing; if the paging lists of some POs in the q POs are not obtained, configure the fourth indication information to indicate Do not reuse.

As shown in Figure 10, assume that the network-side device determines that the second PEI is multiplexed at PO0 and PO4 corresponding to the first paging frame within two DRX cycles, and determines the network-side device according to the ID of the terminal device to be paged Send paging messages at PO0 and PO4, the terminal devices in WUS group2 and WUS group4 associated with PO0 need to wake up at PO0 to receive paging messages, and the terminal devices in WUS group1 and WUS group3 associated with PO0 can Sleep at PO0; terminal devices in WUS group4 associated with PO4 need to wake up at PO4 to receive paging messages, and terminal devices in WUS group1 to WUS group3 associated with PO4 can sleep at PO4, therefore, network-side devices can The second PEI is configured as "0101 0001 1".

S902. If the fourth indication information indicates multiplexing, the terminal device maintains a sleep state or receives a paging state at q POs according to the second PEI.

S903. If the fourth indication information indicates no multiplexing, the terminal device maintains the dormant state or receives the paging state at the first PO among the q POs according to the second PEI, and receives the paging information corresponding to the first PO among the q POs respectively. The third PEI corresponding to each PO after the POs, and each PO located after the first PO among the q POs, maintain a dormant state or receive a paging state according to the corresponding third PEI.

It can be understood that, when the network side device can predict the paging status within q DRX cycles, the network side device may select the second PEI multiplexed at q POs according to the paging status. In the case of multiplexing, the network side device may send only one second PEI at q POs, and the terminal device only needs to receive the second PEI once, thereby saving power consumption. If the paging status within q DRX cycles cannot be predicted, the network-side device can choose not to multiplex the second PEI, so that the network-side device can flexibly and timely page the associations at each PO according to the burst traffic. terminal equipment, thereby reducing paging delay.

It is worth noting that the method flow shown in FIG. 4 and the method flow shown in FIG. 9 can be implemented independently or in combination.

For example, in the third scenario, when the network side device determines to multiplex the second PEI at q POs, for example, as shown in Figure 11, the network side device can also add another bit to the second PEI, using to represent the first indication information. The terminal device monitors paging at q (q=K) PO0s according to the indication of the second PEI until the terminal device successfully receives the first paging message, and when it is determined that the paging message does not carry the terminal device's ID, the terminal device can maintain a dormant state at the remaining POs among the q POs according to the first indication information carried in the second PEI.

Optionally, the present application also provides a fourth possible scenario. In the fourth possible scenario, the network side device configures the eDRX cycle and the fourth PEI for the terminal device. The PTW in the eDRX cycle includes r DRX cycles, the fourth PEI is configured to correspond to one or more POs located at the same position in the q DRX cycles, r≥q≥1, and both q and r are integers. Wherein, the q DRX cycles may be continuous or discontinuous. The fourth PEI includes a bitmap corresponding to each group of terminal devices in each PO.

For example, as shown in FIG. 12 , the fourth PEI corresponds to PO0 and PO4 (4 POs in total) located in the first paging frame within two DRX cycles (q=2). The fourth PEI includes a 16-bit bitmap, respectively indicating the 4 POs (that is, PO0 and PO4 corresponding to the first paging frame in the first DRX cycle, and PO4 corresponding to the first paging frame in the second DRX cycle). 8 groups of terminal equipment in PO0 and PO4). For example, suppose that in the first DRX cycle, the network side device will send paging messages for paging terminal devices in WUS group2 and WUS group4 associated with PO0, and for paging WUS associated with PO4 Paging messages of terminal devices in group4. In the second DRX cycle, the network side device will send a paging message for paging terminal devices in WUS group4 associated with PO0, and a paging message for paging terminal devices in WUS group2 associated with PO4 call message. Therefore, the network side device determines that the fourth PEI can be configured as "0101 0001 0001 0100".

In this scenario, the network side device needs to predict the paging situation at each PO corresponding to the fourth PEI in advance, so that one fourth PEI can be sent at q POs, and the terminal device only needs to receive the fourth PEI once , it can be determined whether the q POs need to wake up to receive the paging message, thereby saving the power consumption of the terminal device.
